SPECIFICATION forming part of Letters Patent No. 395,042, dated December 25, 1888. Application filed May 4, 1888. fierial No. 272,811. (No model.)

To all whom it may concern:

Be it known that we, JOHN SAMUEL DILL- MAN and WILLIAM BLACK KYLE, of Moscow, in the county of Nez Perces and Territory of Idaho, have invented a new and Improvedv Gopher-Exterminator, of which the following is a full, clear, and exact description.

Our invention relates to a device for forcing poisonous fumes or gases into holes in the earth to destroy gophers, rabbits, squirrels, or other burrowing animals; and the invention has for its object to provide a simple, inexpensive, and easily-operative device of this character, which may be used effectively without allowing escape of the fumes toward or around the operator, which, if allowed, would sicken or injure him.

The invention consists in certain novel features of construction of the exterminator, all as hereinafter described and claimed.

Reference is to be had to the accompanying drawing, forming a part of this specification, and which is a longitudinal central sectional elevation of our improved gopher-exterminator, with earth and a burrow therein indicated in dotted lines, and the handle-rod of the plunger or piston partly broken away.

The exterminator consists of two main sections or parts, an air and smoke pump, A, and a fire box or cylinder, B, which are arranged for easy connection with and disconnection from each other by a screw or slip joint, a, so as to readily allow straw or wood, 0, together with a suitable quantity of sulphur, to be placed in the fire-box, which at its outer or lower end is tapered to forni a contracted nozzle, 1), having a smoke-discharge opening, I). The tapering nozzle allows easy insertion of the lire-box into a hole, D, made in the earth by a gopher, rabbit, squirrel, or other burrowing animal.

The pump-section A of the device is made with a barrel or cylinder, E, which is provided with an air and smoke tight piston, F, the rod f ct which plays through a stuffing-box, g, on the head G of the barrel, and is provided with a handle, f, by grasping which the piston may be reciprocated in the barrel. At its lower part the barrel is provided with a partition-plate, H, having a hole, 72-, which is normally closed by a valve, I, which is supported by a lever, .I, fulcrumed in the barrel in a manner to cause its weighted end j to carry the valve against the plate. At one side of it, and near the two extreme positions of the pis- 5 5 ton F, the barrel E is provided with openings e e, communicating with short lateral pipes K L, respectively, and in which are provided apertured partitions is Z, forming seats, against which the inwardly-opening flap-valves M N, hinged in the pipes K L, respectively, are adapted to close by an outward movement. At its upper part, and preferably about opposite the opening e, the barrel E has another side opening, 6 which communicates with the 6 5 interior of the hollow handle 0 of the device, which communicates at its lower end with the interior of the barrel E, below its valve-plate and valve H I, by means of another opening, 6 in the side of the barrel. In the upper part, '0, of the handle 0, and near the barrel E, is fitted an apertured partition-plate,p,forming a seat against which a hinged flap-valve, P, fitted in the handle, may close, said valve opening outward, as shown in the drawing.

The operation of the exterminatoris as follows: After the fire-box B is charged with the combustible material C and sulphur in proper quantity, as above described, and the material is lighted or fired, the air and smoke pump A will be connected with the fire-box at the joint a, and when the fire-box is pushed into a burrowed hole, D, the pump-piston F will be worked by its rod and handle f f which may be done with one-hand of the operator, while his other hand grasps the handle 0 on the pump-barrel to steady the device. On the upward or outward stroke of the piston the valves I M will close and the valves N P will open, and while the air which had previously 0 entered past the valve M is being forced by the rising piston past the valve P and through the hollow handle 0 to the interior of the barrel A, below the closed valve I, a fresh supply of air enters the barrel past the open valve N, and the air forced through the handle 0 will also be forced downward through the combustible material C in the barrel to drive the sulphur-charged smoke into the hole D, On the inward or down stroke of the too valves M I open, and the air, which had just previously entered the barrel A past the valve N, will be forced directly downward through the comlmstible material C, to carry the sul- I opening to the nunp-barrel below said botphur-charg'ed smoke and [fumes into the hole fl). and outward strokes or movements in forcing the deadly fumes into the burrowed hole to exterminate the animals therein, and as the valve 1 remains closed on the upstroke of the a pump, A, and fire-box ll, adapted for d etaele piston and closes prtnnptly after its down- The piston is effective onboth itsinwart'l eonnnunieating' lire-box, said pump provided with air-inlets Controlled by inwardly-open- 'ing valves located at or beyond the extremes of stroke of the pistoma downwa-rdly-open' ing' bottom valve, a hollow eonduit or handle tom valve, and also above or beyond the piston, and an outwardly-opening valve titted to 1 the hollow conduit or handle, substantially as stroke, and as the valve 1 also closes promptly on the (lOWl'iStlOiCC ol' the piston, there willbe i no escape of these fumes from the device tol ward the operator, which, it' allowed, would stupefy or injure him; hence the exterminator may be used with eileetiveness by any person of ordimu-y intelligenee with ease and entire safety.

The eomlnlstible material maybe emi,

ployed with any sul')stanee or com nnnul l for operation substantially as deseribed, for

whieli will when tired generate deadly gases to be forced into the burrow, sulphur being described, For the purposes set forth.

2. The etinnbination, in an exterminator, oi'

able connection,said pump provided with a piston, F, a bottom air-outlet having" a dome wardly-opening valve, I, air-inlets at or beyond the extremes of stroke of the piston and controlled by inwardly-opening' valves M N, respectively, a hollow handle or eonduit, coin'ieeted with the pump-lmrrel above the 3 piston F and below the valve 1, and an outa desirable substance eommonly used For this purpose.

.llaving thus described. our invention, what i we elaun as new, and desire to secure by Letters Patent 1. An exterininator madewitl; apumpand i \vardly-openi'ng valve, P, titted in the handle or conduit O, all eonstrueted and arranged the purposes set forth.
